I've been redesigning the sound booth at the improv comedy club I work at, and decided we needed to update our music system. We have a 200 disc CD changer, which sounds good on paper, but is difficult to work with. A scene might need just the right music, but you have to remember "It's on Disc 165, track 14", and then punch it in, wait for it to cue, etc. etc. etc. So, I found this software. http://www.otsjuke.com It's really cool. It will automatically mix between two songs, will allow you to set up an entire evening of music, and play it perfectly, and will even play two songs off of the same CD at the same time (even one forward and one backward). Download the demo and play with it. Pretty darned cool. It almost makes me want to get back into mobile DJ. Almost, that is!
